CBET- 0828214Pardyjak, Eric - U. UtahCBET-0828206Willemsen, Peter - U. MinnesotaThe objective of this proposal is to increase knowledge for how environment and urban form interact. Its hypothesis is that optimal urban structures and layouts exist which can minimize energy use while also minimizing air pollution exposure.An extremely fast and inexpensive energy use and dispersion modeling tool for urban areas will be developed by building on PIs previous work. The modeling system will utilize the unique computational parallelism afforded by graphics processing units (GPUs, that are regularly utilized in the video game industry), to run many simulations in an effort to train an optimization algorithm for determining optimal designs for urban structures and their layout. This proposed research will also utilize an interactive and immersive virtual environment to provide better understanding and refinement of the complex physical processes associated with the energy balance and pollutant dispersion in an urban setting. Modeling capabilities that will be developed through this work will aid urban planners in developing useful and novel planning strategies to improve the sustainability of modern cities. The PIs will work with urban planners throughout the model development process. These modeling capabilities will also aid architects by providing them with a tool that not only analyzes isolated buildings, but also provides understanding regarding the interaction of multiple buildings during the design process. In addition, this proposal has a substantial outreach component designed to provide a unique educational opportunity for American Indians, Alaskan Natives, and other minorities to learn about various aspects of modeling in environmental engineering. Through our program, American Indian students from Northern Minnesota will be invited to a weeklong interactive learning symposium during each of the three years of the grant.

Minnesotathe该提案的目标是增加有关环境和城市形式相互作用方式的知识。它的假设是，存在最佳的城市结构和布局，可以最大程度地减少能源利用，同时还可以最大程度地减少空气污染的暴露。一种非常快速且廉价的能源利用和分散建模工具将通过PIS先前的工作来开发。建模系统将利用图形处理单元（GPU，经常在视频游戏行业中使用的GPU）提供的独特计算并行性，以运行许多模拟，以努力培训优化算法，以确定城市结构及其布局的最佳设计。这项拟议的研究还将利用互动和沉浸式的虚拟环境，以更好地理解和改进与城市环境中与能量平衡和污染物分散相关的复杂物理过程。通过这项工作将开发的建模能力将有助于城市规划人员制定有用的新型计划策略，以提高现代城市的可持续性。 PI将在整个模型开发过程中与城市规划师合作。这些建模功能还将通过为建筑师提供一种工具来帮助建筑师，该工具不仅可以分析孤立的建筑物，而且还提供了有关在设计过程中多个建筑物相互作用的理解。此外，该提案还具有实质性的外展部分，旨在为美洲印第安人，阿拉斯加原住民和其他少数民族提供独特的教育机会，以了解环境工程中的建模各个方面。通过我们的计划，来自明尼苏达州北部的美洲印第安学生将被邀请在赠款的三年中参加为期一周的互动学习研讨会。
